Container provided with metallic cover and method and apparatus for manufacturing the same

Abstract

This invention relates to a container (10) provided with a metallic cover comprising a plastic container (14) provided with a flanged portion (15) and a metallic cover (11) provided with a peripheral edge portion (12) and having an improved reservation property obtained by improving a material of the container body (14) and the shape thereof, also relates to a method for manufacturing a container provided with a metallic cover comprising the steps of mounting a container body (214) provided with a flanged portion (215) in a recess (267a) of a retainer (267), conveying the container body (214) mounted in the recess (267a) of the retainer (267) and the metallic cover (211) to a seaming device (256), seaming the peripheral portion (212) of the metallic cover (211) to the flanged portion (215) of the container body (214) by the seaming device (256), and discharging the seamed container provided with the metallic cover from the seaming device (256), and further relates to a press-cut device which includes a vertically reciprocating intermediate bed (313) and an upper stationary table (315) disposed above the intermediate bed (313) and in which a pressing device (321) and a cutting device (323) are secured to the intermediate bed (313) and the stationary table (315) and a conveyer (317) is arranged between the pressing device (321) and the cutting device (323).

What is claimed is: 
     
       1. A container seaming device comprising: a turret slidably rotated on a stationary plate and having a plurality of holes for conveying a plastic container provided with a metallic cover retained by a retainer in a manner where said retainer is slidably supported on said stationary plate, communicating with a supply line and a discharge line,   a seaming device having a plurality of seaming rolls arranged above said turret so as to surround said plastic container provided with a metallic cover,   a lifter arranged below said turret so as to upwardly move the plastic container provided with a metallic cover retained by the retainer in one of said plurality of holes when said turret stops,   said retainer having a recess with a shape corresponding to a bottom shape of said plastic container provided with a metallic cover, and   a chuck located above said lifter so as to press said plastic container provided with a metallic cover against said lifter.
